Description

422904 V. Description of the invention (1) The present invention relates to a "concrete construction method for steel-frame buildings and its master mold device", in particular to a construction method and a hanging formwork device for a floor panel. At present, the steel-framed building area has a large number of steels distributed at intervals: refer to Figures 1 and 2]. According to the predetermined floor position, the preparations (10) are respectively assembled with longitudinal steel beams (丄 i ' The transverse steel beams (1 2) 'form a comprehensive grid-like arrangement. Then, the moulding and grouting is carried out layer by layer from bottom to top to complete the concrete steel beams and floor slabs in order. , It is necessary to first set up numerous densely distributed wooden columns on the completed floor to nail the floor formwork of the previous floor and the bottom formwork under the steel beam of the previous floor, and further combine the floor formwork and the bottom formwork. The outer formwork is set between each nail to surround the steel beams. Then stirrups are attached to the periphery of each steel beam, and steel bars are added to the floor formwork for casting concrete. Finally, all the floor formwork, bottom formwork and "Side formwork" completes the concrete steel beams and floor slabs of this floor. Then repeats the above construction steps to carry out the upper-floor mold grouting. Since the traditional method is to set up countless wooden columns from bottom to top Then, the floor formwork, bottom formwork and side formwork of the high place are performed, resulting in slow and difficult construction and the need for a large number of formworkers. When the floor formwork is completed, most formworkers are idle and unable to flexibly allocate manpower. And the construction period is longer, which increases costs. In view of the practical shortcomings of traditional concrete steel beams and floor slab construction, the inventor has continued to seek improvements and supplements according to their crux.

V. Description of the invention (2) What it lacks, in order to find out, and finally complete the method of the present invention and its hanging formwork to install the purpose of the present invention and the floor template of the suspender of the construction side of the floor. After the support members are used, the telescopic rod is used to nail the steel beams and then all the formwork and hangers are removed. The construction work is more sufficient to reduce the formwork worker ’s manpower deployment and avoid the actual construction needs related to the effects of the present invention. Become more clear. First, this method and its lifting formwork are installed, and a third steel frame is installed below the longitudinal steel beams (each horizontal in the first floor area), mainly for sliding support. At this time, the steel bars and the earth steel beams can be placed on the area first. Manpower, work flexibility, can be used for numerous research and analysis, design of concrete steel beams and floor slabs, construction preparation, multi-adjustment for most installations, top dismantling, continuous casting, and floor slabs > shortening construction arrangements Find an explanation of "steel frame placement". That is, in the mentioning and hanging on the side of each fixed, to the top to extend the side template * template, first to assemble, for rapid confirmation, and to avoid interpersonal 〇 to achieve the upward embodiment, " The “steel frame installation” system pin 1) and the horizontal grid arrangement, 4 and 5 make the building mixed with a “mold device”. A horizontal telescopic truss and shrink truss is fixed under the steel beam, and then the hoops are completed to coagulate and do not need to be solid. In order to save the construction and wasting of the purpose of the formwork, and to mix the building with the figure, the steel beams in the first and the vertical direction of the steel beam (the vertical and horizontal direction of the '6) are placed in several places, and the telescopic truss formwork, then flat Supports, concrete, etc. Due to the entire construction period, it can be used, can be used, in accordance with the technical means used and its surface description 'to enable the overall design of concrete steel beams and floor slab construction 2 steel columns (1 〇) 12) and designed to the floor steel beams (1 1), (12 shown in the bottom formwork (2 0).

V. Description of the invention (4) r ′ The arms (4 1) extending outward as shown in Figures 9, 10, " and ^ above are installed at both ends of the upper support (40). The upper support piece (40) has two long circular holes (400) (or a plurality of spaced holes) for fixing holes (4 0 2) of the anti-fall-out pin (4 0) Yang into the branch f (4 丄). 4 〇 丄 and the other side of the support arm (41) is provided with upper and lower stops (43), (44 j, to lean against the upper and lower ends of the upper support (4)) for the adjustment arm (41 f extended position support arm ( 41) The end is also provided with a long round hole (4), for the bolt (40) to be inserted into the fixing hole (4) of the upper and lower supporting pieces (42) of the support (42), and the other side of the upper supporting piece (45) An upper stopper (47) is set to hang on the support arm (41). In a preferred embodiment, the 'supporting member (42) adopts a square tube and is located parallel to the two outer sides of each longitudinal steel beam (1 1) At the bottom of the support (4 2 L, a short wooden post (48) is supported on the horizontal wooden cup (2 3) of the bottom formwork (20), and two sets of oblique facing wedges ( 49) for height adjustment, and the other supporting piece (4 2) uses iron nails to fasten the short supporting post (4 6) before and after the lower supporting piece (4 6). ° Refer to Figure 10, 丄 1'12, each phase The supports (42) adjacent to the longitudinal steel beam (1 1) are two for most parallel telescopic trusses (50). The support plate (51) is straddled, and the telescopic truss (50) has movable inner and outer trusses to adjust the overall length by telescoping. Then, a top template (22) is provided on the surface of the area surrounded by the telescopic trusses (50) ), And then with the telescopic rods (52) standing on the completed floor of the next floor up against the telescopic trusses (50), to form a stable support. Therefore, the vertical steel beam (11) can be supported above ( 40), support arm (41), support 176i-1048.ptd — * ----— ___ Page 9-着 4 2 2 9 0 4 5. Description of the invention (5) pieces (42) and short wooden columns ( 48) 'And as shown in Fig. 13 between the bottom formwork (20) and the top formwork (2 2), a nailed side formwork (2 1) is erected to surround each longitudinal steel beam (ii) «在 更In the preferred embodiment, the bottom formwork (20) and the crossbar (23) can further support the telescopic rod (5 because the transverse steel beam (12) does not need to support the telescopic truss (50), so the transverse steel beam (12) The upper support piece (40), the support arm (41), the support piece (42), and the short wooden post (48) can be omitted, and it can be directly on the bottom template (20) and the top template (22). Side nailing template (2 1). Then for each vertical Tie stirrups (60) on the outer periphery of the transverse steel beam and steel bars (6 1) on all the top formwork (22) [see Figure 14]. At this time, the floor slab and the steel beam concrete (70) can be cast. Please refer to Figure 5] 'Finally, remove all bottom formwork (20), side formwork (21) and top formwork (22) as shown in Figure 16 to complete the entire layer of concrete steel beams and floors. As mentioned in the present invention, the "construction method of concrete steel beams and floor slabs of steel-reinforced buildings and the hanging formwork device thereof" can preliminarily assemble the bottom formwork and the suspender 'and adjust the sliding position, and it is not necessary to first place a wooden column, so the entire formwork is constructed. The operation is more rapid and indeed saves manpower, shortens the construction period, can reduce the formwork worker, and the related formwork construction can be flexibly arranged, and manpower can be flexibly allocated to avoid personnel idle and waste, which can be used by the construction industry and meets the actual construction needs.
